In Belgium March 30, 1936 4 Claims.

The present invention has for its object an independent spinning spindlewith a reversed flyer, that is to say, a spindle adapted to be mountedon a frame without necessitating the precise regulation of a number ofparts of the frame, since such a spindle comprises a fixed support, allthe guiding parts and means for perfect lubrication.

This spindle has a braked bobbin support and a device for the automatichooking of the thread for fresh bobbin formations.

The invention has for its object the formation of bobbins on opened outmetallic tubes.

Such a spindle, with all its accessories, constitutes an independantunit operating in a semiautomatic manner and adapted to be arranged on aspinning frame and preferably on a frame for spinning wet flax.

The accompanying drawing shows diagrammatically by way of nonrestrictiveexample, one method of carrying out the invention.

There is shown in Figure l the assemblage of the parts which constitutea spinning spindle, Figure 2 shows to a larger scale, the support of thetube, the tube itself as also the device for hooking on the thread.

The parts which constitute this device for hooking on the thread areshown in perspective in Figures 3 and 4.

A spindle thus constructed may be easily mounted, avoids all vibrationwhilst working and permits the placing in position of the tubes and theinstantaneous removal of the bobbins, it resists perfectly the action ofwater and is consequently particularly suitable for wet spinning.

The spindle I shown on the annexed drawing cannot rotate owing to knownmethods of guiding and for example, by the arrangement of fiat parts atits base at 2, it is given a rising and falling movement by members towhich it can be loosely connected and it moves in a socket 3 which formsthe casing of the spindle and which can be fixed, owing to a collar 4and a nut 5, on to the frame of a spinning machine.

The upper outer part of this socket serves as a guide for the rotatingpart 6 which receives this movement by any known means, for example, bythe intermediation of a pulley 8.

At its extremity the spindle serves as a support for a part in the formof a cup I5 which is fixed thereon by keys or by any other suitablemeans. It then serves as the axis of rotation for a part IS on which canbe placed the tube IT. The lubrication of this part is ensured by theintroduction of lubricant into a cup l8 provided at the upper part ofthe spindle.

The tube support It carries at its lower part an inverted cup 29 whichprotects a washer IS the material and dimensions of which are chosenaccording to the amount of brake effect desired. This Washer 19 rests ona disc 20, preferably metallic, disposed over the part l5 and securedthereto.

The part ii on which the bobbin forms, is constituted by a metallic tubeheld to the rotating support by one or more springs 2| of known designand shape.

The tube support I6 is secured to the spindle by means of one or morelock projections 22 urged inwardly, by an elastic collar 23, into achannel 24 provided in the spindle itself. As will be seen from Figure2, it is impossible to disengage these projections from the channel aslong as a tube is arranged on this support for the formation of abobbin.

For the automatic engagement of the thread the cup l5 carries hooks 25as shown in Figure 3, while Fig. 4 shows a member 26 having teeth 21which is adapted to be held between 29 and the tube 11.

The thread, which is passed through the hook 28 of fiyer I, firstengages the teeth 25 when the spindle is raised and the tube I'l empty.A few turns of thread are then wound around said tube which, gradually,starts to revolve. Since the hollows of the hooks are in a plane belowthe member 26, the thread continues to wind around the central boss of26; this winding produced at a time when the tube revolves slowly servesas a starting point for the bobbin proper. As soon as the tube starts torevolve rapidly, the centrifugal force projects the free end of thethread from the boss of 26; this end is removed with the bobbin oncompletion thereof.

These spindles, free from vibration, will permit the rapid equipment ofspinning frames without difliculty, the production of which will beincreased.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same is to be performed, I declarethat what I claim is:-

1. In a reversed flyer spinning spindle, a spindle shaft, acircumferentially toothed cup-like member secured to said spindle, aconcentric tubular tube support frictionally connected with the cup-likemember, a disc within the cup-like member and associated with thetubular support, a tube frictionally engaged with said support andresting over the disc, and means for winding thread over said tube.

2. In bobbin winding mechanism including a spindle, a cup secured tosaid spindle, said cup having teeth formed therein laterally, a tubesupport concentrically over the spindle and having a lower flangeresting within the cup over friction material, a toothed disc restingover said flange above the teeth of the cup, a bobbin tube frictionallyretained over the support above the disc, and a reversed flyer forwinding thread onto the tube.

3. In a spinning spindle having a non-rotary spindle and a reversedflyer, thread hooking means secured to the spindle, a thread coveringdisc disposed within the hooking means, a tube support resting over thehooking means and concentrically around the spindle, and a tubefrictionally engaged to the support for receiving the thread.

4. A reversed fiyer spinning spindle, comprising the spindle shaftproper, a. toothed cup-shaped member secured to said shaft, a tubesupport concentric to the shaft and resting on the cup bottom, a threadcovering disc within said cup at a level with the cups teeth, and abobbin tube frictionally engaged over the support.
